# VerifiedKeyEvent

`public final class VerifiedKeyEvent`
`` `extends VerifiedInputEvent` `implements Parcelable`

java.lang.Object
↳ | android.view.VerifiedInputEvent
| ↳ | android.view.VerifiedKeyEvent

KeyEvent that has been verified by the system. The data contained in this class is always a subset of a `KeyEvent`. Use this class to check which data has been confirmed by the system to be authentic. Most applications do not need to use this class.

## Fields

### CREATOR

    public static final Creator<VerifiedKeyEvent> CREATOR

## Public methods

### describeContents

    public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `writeToParcel(android.os.Parcel, int)`, the return value of this method must include the `CONTENTS_FILE_DESCRIPTOR` bit.

Returns
`int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

### equals

    public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

Parameters
`o` | `Object`: This value may be `null`.

Returns
`boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### getAction

    public int getAction ()

The action of this key event. May be either `KeyEvent#ACTION_DOWN` or `KeyEvent#ACTION_UP`.

Returns
`int` | Value is `KeyEvent.ACTION_DOWN`, or `KeyEvent.ACTION_UP`

See also:

- `KeyEvent.getAction()`

### getDownTimeNanos

    public long getDownTimeNanos ()

Retrieve the time of the most recent key down event, in the `SystemClock.uptimeMillis()` time base, but in nanoseconds. If this is a down event, this will be the same as `VerifiedInputEvent#getEventTimeNanos()`.

Returns
`long` |

See also:

- `KeyEvent.getDownTime()`

### getFlag

    public Boolean getFlag (int flag)

Get a specific flag of this key event, if possible. Return null if the flag value could not be checked.

Parameters
`flag` | `int`: the flag of interest

Returns
`Boolean` | Boolean(true) if the key event has the requested flag Boolean(false) if the key event does not have the requested flag null if the flag value could not be checked

See also:

- `KeyEvent.getFlags()`
- `KeyEvent.FLAG_CANCELED`

### getKeyCode

    public int getKeyCode ()

Retrieve the key code of the key event.

Returns
`int` |

See also:

- `KeyEvent.getKeyCode()`

### getMetaState

    public int getMetaState ()

Returns the state of the meta keys.

Returns
`int` | an integer in which each bit set to 1 represents a pressed meta key

See also:

- `KeyEvent.getMetaState()`

### getRepeatCount

    public int getRepeatCount ()

Retrieve the repeat count of the event. For key down events, this is the number of times the key has repeated with the first down starting at 0 and counting up from there. For key up events, this is always equal to zero. For multiple key events, this is the number of down/up pairs that have occurred.

Returns
`int` |

### getScanCode

    public int getScanCode ()

Retrieve the hardware key id of this key event. These values are not reliable and vary from device to device.

Returns
`int` |

See also:

- `KeyEvent.getScanCode()`

### hashCode

    public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal according to the `equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

### writeToParcel

    public void writeToParcel (Parcel dest,
                    int flags)

Flatten this object in to a Parcel.

Parameters
`dest` | `Parcel`: This value cannot be `null`.
`flags` | `int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
